Explanation:

Legal cultivation of opium for medicinal purposes is carried out in India, only in selected areas, under free licensing conditions. India is the world's largest manufacturer of legal opium for the pharmaceutical industry according to the CIA World Factbook. Legal cultivation for medical use is permissible within the ambit of United Nations, Single Convention on Narcotic Drugs 1961.

Each year the Central Government notifies the selected tracts where such cultivation will be permitted, and the general conditions for eligibility of the licence. The essential condition for issue of licence is, fulfillment of minimum qualifying yield (MQY) criterion, specified in number of kilograms per hectare. Cultivators who have tendered at least this quantity in the previous year are eligible for licence
